I want some specific pictures to be uploaded into the proper folder. After some googleing I came across this page
http://doc.silverstripe.org/imagefield
and luckily the last parameter is what I need :-)
But what are all the other ones? First I tried to look through the API docs but I couldn't find any information what the parameters are. Just this page http://api.silverstripe.org/2.4/forms/fields-files/ImageField.html
But that isn't helpful in any way I need it :(
